Find the x-intercepts of the parabola with vertex (-7,45)

1 answer:

3 0

Use the vertex form,
y=a(x-h)^2+ky=a(x+7)^2+45
<span>Use the y-intercept to solve for a</span>-200=a(0+7)^2+45
49a+45=-20049a=-245a=-5

A firm has a fixed cost of $500 in its first year of operation. When the firm produces 100 units of output, its total costs are

HACTEHA [7]

Answer:

option (a) $250

Step-by-step explanation:

Data provided in the question:

Fixed cost = $500

For 100 units produced Total cost = $3,500

For 101 units produced, Total cost = $3,750

Now,

Marginal cost is calculated as:

Marginal cost = $\frac{\textup{Total change in cost of producing more goods}}{\textup{Total change in produced goods}}$

thus,

Marginal cost = $\frac{\textup{Total cost of 101 units - Total cost of 100 units}}{\textup{101-100}}$

Marginal cost = $\frac{\textup{3,750-3,500}}{\textup{1}}$

Marginal cost = $250

Hence,

The correct answer is option (a) $250

An empty cubical carton is side 7cm. Can you fill 1000 cubes of side 1cm in it ?

Shalnov [3]

An empty cubical carton of side 7cm has the volume:
7 x 7 x 7 = 343cm³

A cube of side 1cm has the volume:
1 x 1 x 1 = 1cm³

From this, we can see that a 1000 cubes of side 1cm has the volume:
1000 x 1cm³ = 1000cm³

But we know that the cubical carton of side 7cm only has a volume of 343cm³.

Since 1000cm³ > 343cm³,
you cant fill 1000 cubes of side 1cm in such a carton.

TL;DR
No

Hope this helps

Schach [20]

Answer:

I believe the answer is the second option, t is the independent variable and a is the dependent variable.

Step-by-step explanation:

This is because the amount of juice Marshall can make depends on the number of tomatoes Marshall has. Therefore, a is a dependent variable and option B is the answer.
